Every few months, several counties in North Carolina become the training grounds for the Army’s culminating exercise known as Robin Sage, where aspiring Green Berets face a final test. Named after an OSS operative, Col. Jerry Michael Sage, the four-week exercise takes place in the fictional 50,000 square mile territory of Pineland in the North Carolina woods. The exercise simulates a proxy warfare scenario where candidates work with a guerrilla force, typically led by retired Green Berets, to overthrow an illegitimate government. The exercise tests candidates on a plethora of skills, from medical care to combat operations.
  

Key Points: 

1. Robin Sage is a mandatory four-week exercise for Special Forces candidates, marking the culmination of their training before receiving the Green Beret.
2. The exercise is set in the fictional country of Pineland in North Carolina, spanning about 50,000 square miles.
3. The Army’s Green Berets specialize in training foreign forces, counterterrorism, reconnaissance, and direct-action missions.
4. Prior to Robin Sage, candidates must first undergo the 21-day Special Forces Assessment and Selection, followed by the six-month Special Forces Qualification Course, which has four phases.
5. In the Robin Sage scenario, candidates must collaborate with a guerrilla force to overthrow Pineland’s illegitimate government, testing skills ranging from small-unit tactics to medical care.
